Demonstrations and knowledge of results in motor skill acquisition.
In learning motor skills, different types of information can be utilized to reinforce correct execution of the skill. Over the years, augmented information after the movement (i.e., knowledge of results) has been the most widely studied and has received attention as the most important variable for learning. Recently, however, researchers have begun to focus on modeling or providing information prior to movement as another important aspect of skill learning. The present experiment compared a KR 100% condition with a KR 33% condition, with a final modeling plus KR condition on the acquisition and immediate transfer retention of a timing task. The results showed that all groups reached the same performance level by the end of acquisition. However, over the immediate transfer phase, subjects who had received modeling plus KR during acquisition, increased their errors. Delayed retention produced no significant group effects.
